Caution:
Reason H49 operates within -25°C/+55°C in normal conditions. As heat
within Reason H49 switches is channeled to the enclosure, it is
recommended that 1,5 cm of space be kept between each switch mounted
within the DIN Rail to allow for a small amount of airflow.
A closer spacing will result in higher device operating temperature.
Caution:
The orientation in which the Reason H49 is fitted on the DIN Rail is a key
factor to optimal performance. Reason H49 requires to be installed
vertically on the DIN rail. Other position would lead to inadequate
ventilation and result in increased heat generation.
